Playing the Audio File Stored in the Camera

You can play the audio file stored in the camera using the SNC audio upload tool.

To use this function, you need to make Voice alert active in the Trigger menu of the Administrator menu (page 63).

1 Display the image on the monitor window.

2 Select Voice alert from the trigger drop-down list.

3 Click .

Playback of the audio file starts and the playback sound is output from the speaker connected to the camera.

Switching TCP/UDP Transmission Mode

You can select TCP or UDP as the communication port for the video/audio data.

This function can be used when Mode (video codec mode) (page 39) is set to MPEG4 and the ActiveX viewer is used.

Notes

•The function may not operate correctly when you use personal firewall software or antivirus software on your computer. In that case, disable the software or select the TCP mode.

•If you are using Windows XP Service Pack 2, disable “Windows Firewall” (see page 9).

1 Open the main viewer.

2 Click TCP/UDP Transmission.

The Select TCP/UDP dialog appears.

3 Click one of the buttons TCP, UDP (Unicast) or UDP (Multicast).

TCP: This is normally selected.

When TCP is selected as the communication port, HTTP communication is adopted for video/audio communications.

HTTP is the protocol used for reading the usual Web page.

In an environment capable of reading Web pages, you can watch or listen to the video/audio by selecting the TCP port.

UDP (Unicast): When UDP (Unicast) is selected as the communication port, RTP (Real-time Transport Protocol) is adopted for video/audio communications. Since RTP is the protocol for running video/audio data, the video/audio playback is smoother than when TCP (HTTP) is selected. If a firewall is installed between the camera and the computer, or depending on the network environment, the video/audio may not play back
